Ahhhh...I've been practising and working with stringers! Here are a couple of new glass cabochon toppers, for the interchangeable jewellery system, i.e. they all come with an insert nut on the reverse side of the toppers. Not sure about what I am talking about, then please don't hesitate to contact me for more details.
These cabby-toppers are pretty big, they 36mm onwards. I am using transparent coloured glass with mainly black stringers. I will be listing them either on Etsy or my own web-store over the weekend.
